Now your done with choice1 what you now need to do is to cover choice2 in the part that is shown like this {...}.As the tie case is already dealt with you need to consider the other two options which leads you to an if else statement or if you want to be specific an if else if one. An example for this can be found in the hint of 6/9 unless you already figured this out by now.

So if you have a look at your code you can see that these {}

else if(choice1 === "rock") {
}

should rather wrap the following if else and that for the next case you missed the closing } for the else if and the closing } for the function.
